Fluid simulation not baking, no fluid input object in the scene
As @JtheNinja said above, you didn't set the simulation right.

The "text object" (it must be converted to mesh for this to work) must be set as "fluid", and another surrounding shape (usually a big cube) must be set as "domain", and then baked. As soon as you start baking, the big cube domain will become a fluid-like shape resembling your text:



Without any other setting, or obstacle, this will generate a fluid "text shaped" object that will suddenly splash onto the "ground" (ie: the domain bottom face):



With higher domain resolutions, the fluid-like shape will better fit the text shape, of course (here I used 120 with other standard default fluid settings)
